Constructor Detail

ASTChannel

public ASTChannel(String[] astArray)

Creates a Channel from a String array

Parameters:

astArray - array holding an AST native encoding. Note that a reference to this is kept so any modifications will be seen.

Method Detail

source

protected String source()
                 throws IOException

Read the next line from the array. If past end return null.

Overrides:

source in class uk.ac.starlink.ast.Channel

Throws:

IOException

sink

protected void sink(String line)

Sink function. Note that a String is added to the input array at the current position. If this exceeds the initial storage then the line is quietly thrown away, however the array index is still incremented, so a later query can determine how much storage was required.

Overrides:

sink in class uk.ac.starlink.ast.Channel

setIndex

public void setIndex(int position)

Set the array position index.

getIndex

public int getIndex()

Get the array position index.

getSize

public int getSize()

Get the size of the backing String array.

setArray

public void setArray(String[] astArray)

Replace the String array.

astWrite

public static void astWrite(uk.ac.starlink.ast.AstObject object)
