Method Detail

setArchive

public void setArchive(java.io.File a)
Set the archive that holds this Resource.

Parameters:
a - the archive as a File.

setMode

public void setMode(int mode)
Sets the file or dir mode for this resource.

Parameters:
mode - integer representation of Unix permission mask.

addConfigured

public void addConfigured(ResourceCollection a)
Sets the archive that holds this as a single element Resource collection.

Parameters:
a - the archive as a single element Resource collection.

getArchive

public Resource getArchive()
Get the archive that holds this Resource.

Returns:
the archive as a Resource.

getLastModified

public long getLastModified()
Get the last modified date of this Resource.

Overrides:
getLastModified in class Resource
Returns:
the last modification date.

getSize

public long getSize()
Get the size of this Resource.

Overrides:
getSize in class Resource
Returns:
the long size of this Resource.

isDirectory

public boolean isDirectory()
Learn whether this Resource represents a directory.

Overrides:
isDirectory in class Resource
Returns:
boolean flag indicating whether the entry is a directory.

isExists

public boolean isExists()
Find out whether this Resource represents an existing Resource.

Overrides:
isExists in class Resource
Returns:
boolean existence flag.

getMode

public int getMode()
Get the file or dir mode for this Resource.

Returns:
integer representation of Unix permission mask.

setRefid

public void setRefid(Reference r)
Overrides the super version.

Overrides:
setRefid in class Resource
Parameters:
r - the Reference to set.

compareTo

public int compareTo(Resource another)
Compare this ArchiveResource to another Resource.

Specified by:
compareTo in interface java.lang.Comparable<Resource>
Overrides:
compareTo in class Resource
Parameters:
another - the other Resource against which to compare.
Returns:
a negative integer, zero, or a positive integer as this Resource is less than, equal to, or greater than the specified Resource.

equals

public boolean equals(java.lang.Object another)
Compare another Object to this ArchiveResource for equality.

Overrides:
equals in class Resource
Parameters:
another - the other Object to compare.
Returns:
true if another is a Resource representing the same entry in the same archive.

hashCode

public int hashCode()
Get the hash code for this Resource.

Overrides:
hashCode in class Resource
Returns:
hash code as int.

toString

public java.lang.String toString()
Format this Resource as a String.

Overrides:

Returns:
String representatation of this Resource.

checkEntry

protected final void checkEntry()
                         throws BuildException
Validate settings and ensure that the represented "archive entry" has been established.

Throws:
BuildException

fetchEntry

protected abstract void fetchEntry()
Fetch information from the named entry inside the archive.


dieOnCircularReference

protected void dieOnCircularReference(java.util.Stack<java.lang.Object> stk,
                                      Project p)
Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

If one is included, throw a BuildException created by circularReference.

This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

The general contract of this method is that it shouldn't do anything if checked is true and set it to true on exit.

Overrides:
dieOnCircularReference in class DataType
Parameters:
stk - the stack of references to check.
p - the project to use to dereference the references.
