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

canTypeCheck

public boolean canTypeCheck()

Description copied from interface: ExprCompileContext

Returns whether this compile context can be used for type checking.

Specified by:

canTypeCheck in interface ExprCompileContext

Specified by:

canTypeCheck in class AbstractCompileContext

isCodeSource

public boolean isCodeSource()

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

getSourceType

public java.lang.String getSourceType()

Description copied from class: AbstractCompileContext

Return the source type of the current compile context.

Specified by:

getSourceType in class AbstractCompileContext

getSourceAttributeType

public java.lang.String getSourceAttributeType(java.lang.String name)

Description copied from class: AbstractCompileContext

Return the source attribute type. Many sources like a ViewObject definition may define named attributes. This returns the type of a named attribute.

Specified by:

getSourceAttributeType in class AbstractCompileContext

getSourcePropertyType

public java.lang.String getSourcePropertyType(java.lang.String name)

Description copied from class: AbstractCompileContext

Return the source property type. This is usually a bean property of the source.

Specified by:

getSourcePropertyType in class AbstractCompileContext

getSourceOperationReturnType

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

Description copied from class: AbstractCompileContext

Return the return type of a source operation. Many sources may declare object functions (operations). The returns the return type of a source's operation.

Specified by:

getSourceOperationReturnType in class AbstractCompileContext

getSourceMethodReturnType

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

Description copied from class: AbstractCompileContext

Return the return type of a source method. Many sources may also define custom interfaces (like a row class). This returns the return type of a source's custom interface.

Specified by:

getSourceMethodReturnType in class AbstractCompileContext

getNewValueType

public java.lang.String getNewValueType()

Description copied from class: AbstractCompileContext

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

Specified by:

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.

Specified by:

getOldValueType in class AbstractCompileContext

getEnclosingContext

public ExprCompileContext getEnclosingContext()

Description copied from interface: ExprCompileContext

Returns a compile context that should be used to resolve any types that that are defined by the enclosing variable/property/method.

This will be invoked once by the type checker after it resolves an unbound variable/property/method. This method may be used to pass a compile context back to the compile context that will be later used to evaluate any other types in the enclosing context.

Specified by:

getEnclosingContext in interface ExprCompileContext

Overrides:

getEnclosingContext 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
