Field Detail

mLogger

static final oracle.adf.share.logging.ADFLogger mLogger

For internal use only. Application developers should not use this

Method Detail

getPath

java.lang.String getPath()

A dot separated path that may be used to lookup the ExprDef within the ExprDef's owning compnent. See ComponentOperationsManager#findExprDef.

getExpressionSource

java.lang.String getExpressionSource()

Deprecated. since 12.2.1. Using this may result in a performance issue. If necessary, use the CodeSource to access the expression source text.

The source string of the expression.

getTrustMode

ExprEval.TrustMode getTrustMode()

The trust mode for the expression.

hasReturn

boolean hasReturn()

If the expression has a return value.

getExprIdentifier

java.lang.String getExprIdentifier()

A unique identfier for the expression.

getCacheKey

java.lang.String getCacheKey(java.lang.String exprStr)

The key to be used for caching compiled expression instances.

Returns:

a cacheKey. If null then the compiled expression will not be cached.

isOperationsExpression

boolean isOperationsExpression()

If the expression defines operations.

getScriptClassName

java.lang.String getScriptClassName(java.lang.String exprStr)

Deprecated. use getExpressionClassName instead

Returns the name used for the expression class.

getExpressionClassName

java.lang.String getExpressionClassName()

Returns the name used for the expression class.

getTypeCheckedMode

ExprEval.TypeCheckedMode getTypeCheckedMode()

Returns whether the expresion should be type checked when type checking is enabled for the groovy compiler.

Returns:

ExprEval.TypeCheckedMode.always if the expr should always be type checked ExprEval.TypeCheckedMode.never if the expr should never be typ checked ExprEval.TypeCheckedMode.defer if type checking is dependent upon the application configuration

getOwnerType

OwnerType getOwnerType()

Returns the type of object that owners the expression class.

getCodeSource

CodeSource getCodeSource()

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

getTriggerType

java.lang.String getTriggerType()

Return the trigger type.

Returns:

null if this is not a trigger expression.

supportsAnnotation

boolean supportsAnnotation()

Indicates whether ADF can use an expression annotation to select the expression method for invocation. This is required for some internal expression usages that are not uniquely identified by the annotation. In those cases the framework will use the more unique expression identifier to select the method invocation target.

getProperty

java.lang.Object getProperty(java.lang.String name)
