doWrite
protected void doWrite(java.io.DataOutputStream dos) throws java.io.IOException
- Specified by:
doWrite
in classClassFileEntry
- Throws:
java.io.IOException
-
equals
public boolean equals(java.lang.Object obj)
- Specified by:
equals
in classClassFileEntry
-
getAttributeName
protected CPUTF8 getAttributeName()
-
getLength
protected abstract int getLength()
-
getLengthIncludingHeader
protected int getLengthIncludingHeader()
Answer the length of the receiver including its header (the u2 for the attribute name and the u4 for the attribute length). This is relevant when attributes are nested within other attributes - the outer attribute needs to take the inner attribute headers into account when calculating its length.- Returns:
- int adjusted length
-
getNestedClassFileEntries
protected ClassFileEntry[] getNestedClassFileEntries()
- Overrides:
getNestedClassFileEntries
in classClassFileEntry
-
hasBCIRenumbering
public boolean hasBCIRenumbering()
Answer true if the receiver needs to have BCI renumbering applied to it; otherwise answer false.- Returns:
- boolean BCI renumbering required
-
isSourceFileAttribute
public boolean isSourceFileAttribute()
Answer true if the receiver is a source file attribute (which gets special handling when the class is built); otherwise answer false.- Returns:
- boolean source file attribute
-
hashCode
public int hashCode()
- Specified by:
hashCode
in classClassFileEntry
-
resolve
protected void resolve(ClassConstantPool pool)
Description copied from class:ClassFileEntry
Allows the constant pool entries to resolve their nested entries.- Overrides:
resolve
in classClassFileEntry
- Parameters:
pool
- TODO
-
writeBody
protected abstract void writeBody(java.io.DataOutputStream dos) throws java.io.IOException
- Throws:
java.io.IOException
