Class GenericObjectType

java.lang.Object

org.apache.bcel.generic.Type

org.apache.bcel.generic.ReferenceType

org.apache.bcel.generic.ObjectType

edu.umd.cs.findbugs.ba.generic.GenericObjectType

All Implemented Interfaces:

java.io.Serializable

public class GenericObjectType
extends org.apache.bcel.generic.ObjectType

Extension to ObjectType that includes additional information about the generic signature.

A GenericObjectType is either a parameterized type e.g. List<String>, or a type variable e.g. T.

This class cannot be initialized directly. Instead, create a GenericObjectType by calling GenericUtilities.getType(String) and passing in the bytecode signature for the type.

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class org.apache.bcel.generic.ObjectType

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class org.apache.bcel.generic.ObjectType

getUpperBound

public org.apache.bcel.generic.Type getUpperBound()

getExtension

public org.apache.bcel.generic.Type getExtension()

Returns:

Returns the extension.

getVariable

public java.lang.String getVariable()

Returns:

Returns the variable.

getTypeCategory

public GenericUtilities.TypeCategory getTypeCategory()

Get the TypeCategory that represents this Object

See Also:

GenericUtilities.TypeCategory

hasParameters

public boolean hasParameters()

Returns:

true if this GenericObjectType represents a parameterized type e.g. List<String>. This implies that isVariable() is falses

getNumParameters

public int getNumParameters()

Returns:

the number of parameters if this is a parameterized class, 0 otherwise

getParameterAt

public org.apache.bcel.generic.ReferenceType getParameterAt(int index)

Parameters:

index - should be less than getNumParameters()

Returns:

the type parameter at index

getParameters

public java.util.List<? extends org.apache.bcel.generic.ReferenceType> getParameters()

getObjectType

public org.apache.bcel.generic.ObjectType getObjectType()

Returns:

the underlying ObjectType for this Generic Object

toString

public java.lang.String toString(boolean includeGenerics)

Return a string representation of this object. (I do not override toString() in case any existing code assumes that this object is an ObjectType and expects similar string representation. i.e. toString() is equivalent to toString(false))

Parameters:

includeGenerics - if true then the string includes generic information in this object. Otherwise this returns the same value as ObjectType.toString()

toString

public java.lang.String toString()

Overrides:

toString in class org.apache.bcel.generic.Type

toPlainString

public java.lang.String toPlainString()

getGenericParametersAsString

public java.lang.String getGenericParametersAsString()
