Interface ExprCodeSource

All Known Implementing Classes:

CodeSourceImpl

public interface ExprCodeSource

Manages an expression script. A code source may contain the expression source for many expression usages. Each expression source is defined as a separate method in the code source. The expression identifier is used to identify each expession method.

Code sources are always compiled as a single class.

Field Detail

mLogger

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

For internal use only. Application developers should not use this

DEFAULT_CODE_SOURCE_NAME

static final java.lang.String DEFAULT_CODE_SOURCE_NAME

The name of the built-in default, static code source. Unmigrated expressions that are loaded from XML are added to the default code soure.

Constant Field Values

DYNAMIC_CODE_SOURCE_NAME

static final java.lang.String DYNAMIC_CODE_SOURCE_NAME

The name of the built-in dynamic code source. Any expressions that are added programmatically are automatically added ot the dyamic code source

Constant Field Values

PERSONALIZED_CODE_SOURCE_NAME

static final java.lang.String PERSONALIZED_CODE_SOURCE_NAME

The name of the built-in personalization code source. The source of all personalized expression usages is loaded into this code source.

See Also:

Constant Field Values

TMP_CODE_SOURCE_NAME

static final java.lang.String TMP_CODE_SOURCE_NAME

The name of the built-in temporary code source. Temporary code sources are automatically created for expression owners that do not have a parent. A temporary code source will always have only one expression.

Method Detail

getName

java.lang.String getName()

The code source name. An ADF business component may define more than one named code source.

getClassName

java.lang.String getClassName()

The name of the class that will be generated by the compiler for the code source.

getCacheKey

java.lang.Object getCacheKey()

The key that should be used to cache the byte code that is generated for the code source. A null key indicates that a cache should not be used.

hasExpression

boolean hasExpression(ExprDef exprDef)

Return true if the CodeSource defines an expression for the specified expresmion.

Parameters:

exprDef - an expression def. If null this will return true if the CodeSource defines any expression.
