GenericVariable

GenericVariable ApplyPatches

(qPatches)

Applies a patch to the properties of a variable. Allows an update to some of the properties. It should not be possible to patch "/qInfo/qId", and it will be forbidden in the near future.

Applying a patch takes less time than resetting all the properties.

Parameters

  • qPatchesarray of objects
    Required

    Array of patches.

    Show qPatches properties
    • qOpstring

      Can be one of: "add""remove""replace"

    • qPathstring

      Path to the property to add, remove or replace.

    • qValuestring

      This parameter is not used in a remove operation. Corresponds to the value of the property to add or to the new value of the property to update. Examples: "false", "2", ""New title""

GenericVariable GetProperties

()

Shows the properties of an object.

If the member **delta** is set to true in the request, only the delta is retrieved.
The following is always returned in the output:

Response

  • qPropobject
    Show qProp properties
    • qInfoobject
      Show qInfo properties
      • qIdstring

        Identifier of the object. If the chosen identifier is already in use, the engine automatically sets another one. If an identifier is not set, the engine automatically sets one. This parameter is optional.

      • qTypestring

        Type of the object. This parameter is mandatory.
    • qMetaDefobject

      Used to collect meta data.

      Properties

      Semantic type with an empty structure.

    • qNamestring

      Name of the variable. The name must be unique. This parameter is mandatory.

    • qCommentstring

      Comment related to the variable. This parameter is optional.

    • qNumberPresentationobject

      Sets the formatting of a field. The properties of qFieldAttributes and the formatting mechanism are described below.

      Formatting mechanism

      The formatting mechanism depends on the type set in qType, as shown below:

      In case of inconsistencies between the type and the format pattern, the format pattern takes precedence over the type.

      Type is DATE, TIME, TIMESTAMP or INTERVAL

      The following applies:

      • If a format pattern is defined in qFmt , the formatting is as defined in qFmt .
      • If qFmt is empty, the formatting is defined by the number interpretation variables included at the top of the script ( TimeFormat , DateFormat , TimeStampFormat ).
      • The properties qDec , qThou , qnDec , qUseThou are not used.

      Type is INTEGER

      The following applies:

      • If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the formatting mechanism uses the number interpretation variables included at the top of the script ( DecimalSep and ThousandSep ).
      • If no format pattern is defined in qFmt , no formatting is applied. The properties qDec , qThou , qnDec , qUseThou and the number interpretation variables defined in the script are not used .

      Type is REAL

      The following applies:

      • If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the engine uses the number interpretation variables included at the top of the script ( DecimalSep and ThousandSep ).
      • If no format pattern is defined in qFmt , and if the value is almost an integer value (for example, 14,000012), the value is formatted as an integer. The properties qDec , qThou , qnDec , qUseThou are not used.
      • If no format pattern is defined in qFmt , and if qnDec is defined and not 0, the property qDec is used. If qDec is not defined, the variable DecimalSep defined at the top of the script is used.
      • If no format pattern is defined in qFmt , and if qnDec is 0, the number of decimals is 14 and the property qDec is used. If qDec is not defined, the variable DecimalSep defined at the top of the script is used.

      Type is FIX

      The following applies:

      • If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the engine uses the number interpretation variables included at the top of the script ( DecimalSep and ThousandSep ).
      • If no format pattern is defined in qFmt , the properties qDec and qnDec are used. If qDec is not defined, the variable DecimalSep defined at the top of the script is used.

      Type is MONEY

      The following applies:

      • If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the engine uses the number interpretation variables included at the top of any script ( MoneyDecimalSep and MoneyThousandSep ).
      • If no format pattern is defined in qFmt , the engine uses the number interpretation variables included at the top of the script ( MoneyDecimalSep and MoneyThousandSep ).

      Type is ASCII

      No formatting, qFmt is ignored.

      Show qNumberPresentation properties
      • qTypestring

        Can be one of: "U""A""I""R""F""M""D""T""TS""IV"

      • qnDecinteger

        Number of decimals. Default is 10.

        default = 10, format = int32, default = 10

      • qUseThouinteger

        Defines whether or not a thousands separator must be used. Default is 0.

        default = 0, format = int32, default = 0

      • qFmtstring

        Defines the format pattern that applies to qText . Is used in connection to the type of the field (parameter qType ). For more information, see Formatting mechanism. Example: YYYY-MM-DD for a date.

      • qDecstring

        Defines the decimal separator. Example: .

      • qThoustring

        Defines the thousand separator (if any). Is used if qUseThou is set to 1. Example: ,
    • qIncludeInBookmarkboolean

      Set this property to true to update the variable when applying a bookmark. The variable value will be persisted in the bookmark. The value of a variable can affect the state of the selections. Script variables cannot be persisted in the bookmark. The default value is false.

      default = false

    • qDefinitionstring

      Definition of the variable.
