java.lang.Object

org.refcodes.console.AbstractCondition

All Implemented Interfaces:

org.refcodes.component.Resetable, Condition, Syntaxable, SyntaxUsage

Direct Known Subclasses:

AndConditionImpl, OptionalConditionImpl, OrConditionImpl, XorConditionImpl

public abstract class AbstractCondition
extends java.lang.Object
implements Condition

The AbstractCondition is an abstract implementation of an Condition providing the boiler plate when implementing the Condition interface.

<V> V	get(java.lang.String aAlias)	Searches for a value being set for the given for given alias in the syntax tree parsing the command line arguments; if a node in the syntax tree has a value for the given alias, then this value is returned.

Constructor Detail

AbstractCondition

public AbstractCondition(Syntaxable... aElements)

Instantiates a new abstract condition.

Parameters:

aElements - the elements

Method Detail

toSyntax

public java.lang.String toSyntax(SyntaxNotation aSyntaxNotation)

This method is to be called from inside the Syntaxable hierarchy; use the method SyntaxUsage.toUsage(SyntaxNotation) in case you invoke syntax retrieval from the root Syntaxable. Returns the human readable (verbose) syntax of this Syntaxable instance including, in case of being a node in the syntax tree (such as a Condition, the syntax of the child Syntaxable instances. ATTENTION: As of different parenthesis settings for some notations regarding the root Syntaxable and the child Syntaxables, the method Syntaxable.toSyntax(SyntaxNotation) is called from inside the Syntaxable hierarchy. In case the syntax is to be retrieved from the root Syntaxable, then the applicable method to be called is SyntaxUsage.toUsage(SyntaxNotation), as for some notations it will for example not create the most outer braces.

Specified by:

toSyntax in interface Syntaxable

Parameters:

aSyntaxNotation - The syntax notation used for generating the command line arguments syntax.

Returns:

The human readable (verbose) command line arguments syntax.

reset

public void reset()

Specified by:

reset in interface org.refcodes.component.Resetable

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toOperands

public java.util.List<? extends Operand<?>> toOperands()

Traverses the hierarchy of Conditions and collects all therein found Operands and sub-types such as the Switch or the Option. This is most useful when creating a list of Options, Switches and Operands when printing out detailed help.

Specified by:

toOperands in interface Condition

Returns:

The according Operand elements.

getChildren

protected java.util.List<Syntaxable> getChildren()

Gets the children.

Returns:

the children

addChild

protected void addChild(Syntaxable aArgumentizer)

Adds the child.

Parameters:

aArgumentizer - the argumentizer

get

public <V> V get(java.lang.String aAlias)

Searches for a value being set for the given for given alias in the syntax tree parsing the command line arguments; if a node in the syntax tree has a value for the given alias, then this value is returned.

Specified by:

get in interface Syntaxable

Type Parameters:

V - The type of the value being expected.

Parameters:

aAlias - The alias for which to seek for a value being set.

Returns:

The according value or null if none has been set for the given alias.

toUsage

public java.lang.String toUsage(SyntaxNotation aSyntaxNotation)

Description copied from interface: SyntaxUsage

Returns the human readable (verbose) syntax of implementing class ATTENTION: As of different parenthesis settings for some notations regarding the root Syntaxable and the child Syntaxables, the method Syntaxable.toSyntax(SyntaxNotation) is called from inside a Syntaxable hierarchy. In case the syntax is to be retrieved from the root Syntaxable or an encapsulating and different type, then the applicable method to be called is SyntaxUsage.toUsage(SyntaxNotation), as for some notations it will for example not create the most outer braces.

Specified by:

toUsage in interface SyntaxUsage

Parameters:

aSyntaxNotation - The syntax notation used for generating the command line arguments syntax.

Returns:

The human readable (verbose) command line arguments syntax.
