Class CompactTypeStructureRepresentation

java.lang.Object
  org.aspectj.ajdt.internal.core.builder.CompactTypeStructureRepresentation

All Implemented Interfaces:

IBinaryType, IDependent, IGenericType

public class CompactTypeStructureRepresentation
extends java.lang.Object
implements IBinaryType

Used to determine if a type has structurally changed during incremental compilation. At the end of compilation we create one of these objects using the bytes for the class about to be woven. On a subsequent incremental compile we compare the new form of the class with a previously stored CompactTypeStructureRepresentation instance. A structural change will indicate we need to do recompile other dependent types.

Method Detail

getMissingTypeNames

public char[][][] getMissingTypeNames()

Description copied from interface: IBinaryType

Answer the list of missing type names which were referenced from the problem classfile. This list is encoded via an extra attribute.

Specified by:

getMissingTypeNames in interface IBinaryType

getEnclosingTypeName

public char[] getEnclosingTypeName()

Description copied from interface: IBinaryType

Answer the resolved name of the enclosing type in the class file format as specified in section 4.2 of the Java 2 VM spec or null if the receiver is a top level type. For example, java.lang.String is java/lang/String.

Specified by:

getEnclosingTypeName in interface IBinaryType

getModifiers

public int getModifiers()

Description copied from interface: IGenericType

Answer an int whose bits are set according the access constants defined by the VM spec. NOTE 1: We have added AccDeprecated & AccSynthetic. NOTE 2: If the receiver represents a member type, the modifiers are extracted from its inner class attributes.

Specified by:

getModifiers in interface IGenericType

getGenericSignature

public char[] getGenericSignature()

Description copied from interface: IBinaryType

Answer the receiver's signature which describes the parameter & return types as specified in section 4.4.4 of the Java 2 VM spec 3rd edition. Returns null if none.

Specified by:

getGenericSignature in interface IBinaryType

Returns:

the receiver's signature, null if none

getEnclosingMethod

public char[] getEnclosingMethod()

Description copied from interface: IBinaryType

Answer the enclosing method (including method selector and method descriptor), or null if none. For example, "foo()Ljava/lang/Object;V"

Specified by:

getEnclosingMethod in interface IBinaryType

getInterfaceNames

public char[][] getInterfaceNames()

Description copied from interface: IBinaryType

Answer the resolved names of the receiver's interfaces in the class file format as specified in section 4.2 of the Java 2 VM spec or null if the array is empty. For example, java.lang.String is java/lang/String.

Specified by:

getInterfaceNames in interface IBinaryType

isAnonymous

public boolean isAnonymous()

Description copied from interface: IBinaryType

Answer true if the receiver is an anonymous class. false otherwise

Specified by:

isAnonymous in interface IBinaryType

sourceFileName

public char[] sourceFileName()

Description copied from interface: IBinaryType

Answer the source file attribute, or null if none. For example, "String.java"

Specified by:

sourceFileName in interface IBinaryType

isLocal

public boolean isLocal()

Description copied from interface: IBinaryType

Answer true if the receiver is a local class. false otherwise

Specified by:

isLocal in interface IBinaryType

isMember

public boolean isMember()

Description copied from interface: IBinaryType

Answer true if the receiver is a member class. false otherwise

Specified by:

isMember in interface IBinaryType

getSuperclassName

public char[] getSuperclassName()

Description copied from interface: IBinaryType

Answer the resolved name of the receiver's superclass in the class file format as specified in section 4.2 of the Java 2 VM spec or null if it does not have one. For example, java.lang.String is java/lang/String.

Specified by:

getSuperclassName in interface IBinaryType

getFileName

public char[] getFileName()

Description copied from interface: IDependent

Answer the file name which defines the type. The path part (optional) must be separated from the actual file proper name by a separator suitable for the type (java.io.File.separator for example), e.g. "c:\\source\\com\\p\\X.java" or "/com/p/Y.java". The path to the zip or jar file (optional) must be separated from the actual path part by JAR_FILE_ENTRY_SEPARATOR, e.g. "c:\\lib\\some.jar|/com/p/X.class" or "/lib/some.zip|/com/q/Y.class". The proper file name includes the suffix extension (e.g. ".java") e.g. "c:/org.aspectj.org.eclipse.jdt/internal/compileri/env/IDependent.java" Return null if no file defines the type.

Specified by:
