flags in interface CodeInstance

formalTypes

public java.util.List formalTypes()

Description copied from interface: ProcedureInstance

List of formal parameter types.

Specified by:

formalTypes in interface ProcedureInstance

Returns:

A list of Type.

setContainer

public void setContainer(ReferenceType container)

Parameters:

container - The container to set.

setFlags

public void setFlags(Flags flags)

Parameters:

flags - The flags to set.

setFormalTypes

public void setFormalTypes(java.util.List formalTypes)

Specified by:

setFormalTypes in interface ProcedureInstance

Parameters:

formalTypes - The formalTypes to set.

setThrowTypes

public void setThrowTypes(java.util.List throwTypes)

Specified by:

setThrowTypes in interface ProcedureInstance

Parameters:

throwTypes - The throwTypes to set.

hashCode

public int hashCode()

Overrides:

hashCode in class TypeObject_c

public boolean equalsImpl(TypeObject o)

Description copied from class: TypeObject_c

Default implementation is pointer equality.

Specified by:

equalsImpl in interface TypeObject

Overrides:

TypeObject_c.equalsImpl(TypeObject), Object.hashCode()

listIsCanonical

protected boolean listIsCanonical(java.util.List l)

moreSpecific

public final boolean moreSpecific(ProcedureInstance p)

Description copied from interface: ProcedureInstance

Return true if this is more specific than pi in terms of method overloading.

Specified by:

moreSpecific in interface ProcedureInstance

moreSpecificImpl

public boolean moreSpecificImpl(ProcedureInstance p)

Returns whether this is more specific than p, where more specific is defined as JLS 15.12.2.2.

Note: There is a fair amount of guesswork since the JLS does not include any info regarding Java 1.2, so all inner class rules are found empirically using jikes and javac.

Specified by:

moreSpecificImpl in interface ProcedureInstance

hasFormals

public final boolean hasFormals(java.util.List formalTypes)

Returns true if the procedure has the given formal parameter types.

Specified by:

hasFormals in interface ProcedureInstance

hasFormalsImpl

public boolean hasFormalsImpl(java.util.List formalTypes)

Returns true if the procedure has the given formal parameter types.

Specified by:

hasFormalsImpl in interface ProcedureInstance

throwsSubset

public final boolean throwsSubset(ProcedureInstance p)

Returns true iff this throws fewer exceptions than p.

Specified by:

throwsSubset in interface ProcedureInstance

throwsSubsetImpl

public boolean throwsSubsetImpl(ProcedureInstance p)

Returns true iff this throws fewer exceptions than p.

Specified by:

throwsSubsetImpl in interface ProcedureInstance

callValid

public final boolean callValid(java.util.List argTypes)

Returns true if a call can be made with the given argument types.

Specified by:

callValid in interface ProcedureInstance

callValidImpl

public boolean callValidImpl(java.util.List argTypes)
