Method Detail

getCodeSource

ExprCodeSource getCodeSource()

Returns the code source that contains the code for this expression.

getCodeSourceName

java.lang.String getCodeSourceName()

Returns the CodeSourceName for this expression.

getContentType

java.lang.String getContentType()

Return the MIME content type of the expression's script text. This may be used to select a script engine to evalaute/invoke the expression.

getScriptReader

java.io.Reader getScriptReader()

Deprecated. since 11.1.1.9.20. Use getCodeSource().getScriptReader() instead.

getScriptText

java.lang.String getScriptText()

Returns the script text for this expression definition. If the definiton is resolved to a CodeSource then the this will shred the CodeSource to return the expression definition's sub program.

getFunctionName

java.lang.String getFunctionName()

Return the name of the script function that should be invoked when evalauting the expression definition.

Returns:

return null if the expression script should be evalauted.

getTrustMode

@Concealed
ExprEval.TrustMode getTrustMode(java.lang.String functionName)

For internal use only. Application developers should not use this

calculateOffset

@Concealed
int calculateOffset()

The expression's "offset" within a CodeSource. Exception handling may use the offset to adjust stack line numbers. For example, for triggers that are dynamically added to a CodeSource, the exception handling may use the offset so that the first line of the trigger is reported as line 1 in the stack. This is required if DT presents triggers as scripts while the RT compiles the triggers into functions.

getDefScope

@Concealed
int getDefScope()

For internal use only. Application developers should not use this

getClassData

@Concealed
java.util.Map<java.lang.String,byte[]> getClassData(java.lang.String name)

For internal use only. Application developers should not use this

storeClassData

@Concealed
void storeClassData(java.lang.String name,
                               byte[] classData)

For internal use only. Application developers should not use this

isDynamicCodeSourceEnabled

@Concealed
boolean isDynamicCodeSourceEnabled()

For internal use only. Application developers should not use this
