Method Detail

getExprDef

public ExprDef getExprDef()

Description copied from interface: ExprCompileContext

Return the definition of the expressio that is compiling.

Specified by:

getExprDef in interface ExprCompileContext

Specified by:

getExprDef in class AbstractCompileContext

getStructureDefinition

public StructureDefinition getStructureDefinition()

Description copied from interface: ExprCompileContext

Return the oracle.binding.meta.StructureDefnition of the compile context. For example, when compiling an entity validation rule this should return the StructureDefinition of the entity.

Specified by:

getStructureDefinition in interface ExprCompileContext

Overrides:

getStructureDefinition in class AbstractCompileContext

isTypeChecked

public boolean isTypeChecked()

Description copied from interface: ExprCompileContext

Returns whether type checking should be performed in this compile context.

Specified by:

isTypeChecked in interface ExprCompileContext

Overrides:

isTypeChecked in class AbstractCompileContext

isCodeSource

public boolean isCodeSource()

getMethodReturnType

public java.lang.String getMethodReturnType(java.lang.String receiver,
                                            java.lang.String name,
                                            java.lang.String[] argtypes,
                                            java.lang.String[] argvals)

Description copied from interface: ExprCompileContext

Return the return type of the given method.

Invoked by the type checker if it cannot resolve the specified method.

Specified by:

getMethodReturnType in interface ExprCompileContext

Overrides:

getMethodReturnType in class AbstractCompileContext

getGlobalOperationReturnType

public java.lang.String getGlobalOperationReturnType(java.lang.String name,
                                                     java.lang.String... argtypes)

Description copied from interface: ExprCompileContext

Return the type of the given global operations.

Specified by:

getGlobalOperationReturnType in interface ExprCompileContext

Specified by:

getGlobalOperationReturnType in class AbstractCompileContext

createExtendedType

protected ExprCompileContext createExtendedType(StructureDefinition structureDefinition)

Description copied from class: AbstractCompileContext

Creates a new compile context for the specified structureDefinition. The extended type will be stored by the type checker and used to resolve properties or methods of nested AST nodes. For example, assume an emp context and the expression 'dept.deptno'. The compiler will inovke createExtendedType to create an extended type with dept structure for the 'dept' expression. The extended type compile context will be stored and used later to check the deptno property of the 'dept' expression.

Overrides:

createExtendedType in class AbstractCompileContext

Returns:

a compile context. The abstract compile context will return a "default" compile context for the specified structure. A concrete compile context may override this to return a compile context of the concrete type.

getNewValueType

public java.lang.String getNewValueType()

Description copied from class: AbstractCompileContext

In validator contexts this returns the type of the new attribute or row.

Overrides:

getNewValueType in class AbstractCompileContext

getOldValueType

public java.lang.String getOldValueType()

Description copied from class: AbstractCompileContext

In validator contexts this returns the type of the new attribute or row.

Overrides:

getOldValueType in class AbstractCompileContext

getExprTrustSupplier

public ExprTrustSupplier getExprTrustSupplier()

Description copied from interface: ExprCompileContext

Return the security policiy that is associated with this context.

Specified by:

getExprTrustSupplier in interface ExprCompileContext

Overrides:

getExprTrustSupplier in class AbstractCompileContext
