public class NamedHashToks
extends AbstractAssignment
implements Theable

This class provides an implementation for the hash-toks valued primitives. It sets the named pair register to the value given, and as a side effect all prefixes are zeroed.

Example

 \myhash{ {key1}{value1} {key2}{value2} {key3}{value3} ...}
 \myhash={ {key1}{value1} {key2}{value2} {key3}{value3} ...}

Constructor Detail

NamedHashToks

public NamedHashToks(java.lang.String name)
Creates a new object.

Parameters:
name - the name for debugging
Method Detail

assign

public void assign(Flags prefix,
                   Context context,
                   TokenSource source,
                   Typesetter typesetter)
            throws InterpreterException
Description copied from class: AbstractAssignment
The method assign is the core of the functionality of execute(). This method is preferable to execute() since the execute() method provided in this class takes care of \afterassignment and \globaldefs as well.

Specified by:
assign in class AbstractAssignment
Parameters:
prefix - the prefix controlling the execution
context - the interpreter context
source - the token source
typesetter - the typesetter
Throws:
InterpreterException - in case of an error

AbstractAssignment.assign( de.dante.extex.interpreter.Flags, de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

the

public Tokens the(Context context,
                  TokenSource source,
                  Typesetter typesetter)
           throws InterpreterException
Description copied from interface: Theable
This method is the getter for the description of the primitive.

Specified by:
the in interface Theable
Parameters:
context - the interpreter context
source - the source for further tokens to qualify the request
typesetter - the typesetter to use
Returns:
the description of the primitive as list of Tokens
Throws:
InterpreterException - in case of an error

Theable.the( de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, Typesetter)

getKey

protected java.lang.String getKey(Context context,
                                  TokenSource source)
                           throws InterpreterException
Return the key (the name of the primitive) for the register.

Parameters:
context - the context
source - the source
Returns:
the key
Throws:
InterpreterException - in case of an error.
