getAllocationStatements

public List<SSAInstruction> getAllocationStatements()

getInvokeStatements

public List<SSAInstruction> getInvokeStatements()

equals

public boolean equals(Object obj)

Two specialized methods can be different, even if they represent the same source method. So, revert to object identity for testing equality. TODO: this is non-optimal; could try to re-use specialized methods that have the same context.

Overrides:

equals in class SyntheticMethod

See Also:

• Object.equals(java.lang.Object)

hashCode

public int hashCode()

Overrides:

hashCode in class SyntheticMethod

getStatements

public SSAInstruction[] getStatements()

Overrides:

getStatements in class SyntheticMethod

getDeclaringClass

public IClass getDeclaringClass()

Description copied from interface: IMember

Return the object that represents the declaring class for this member.

Specified by:

getDeclaringClass in interface IMember

Overrides:

getDeclaringClass in class SyntheticMethod

Returns:

the object that represents the declaring class for this member.

getNumberOfParameters

public int getNumberOfParameters()

Description copied from interface: IMethod

Method getNumberOfParameters. This result includes the "this" pointer if applicable

Specified by:

getNumberOfParameters in interface IMethod

Overrides:

getNumberOfParameters in class SyntheticMethod

getParameterType

public TypeReference getParameterType(int i)

Description copied from interface: IMethod

By convention, for a non-static method, getParameterType(0) is the this pointer

Specified by:

getParameterType in interface IMethod

Overrides:

getParameterType in class SyntheticMethod

makeIR

public IR makeIR(Context C,
 SSAOptions options)

Description copied from class: SyntheticMethod

Most subclasses should override this.

Overrides:

makeIR in class SyntheticMethod

Parameters:

C - TODO

options - options governing IR conversion
