Class LookupNumberControl<T extends Number>

java.lang.Object

to.etc.domui.component.lookup.BaseAbstractLookupControlImpl<String>

to.etc.domui.component.lookup.LookupNumberControl<T>

All Implemented Interfaces:

ILookupControlInstance<String>

public class LookupNumberControl<T extends Number>
extends BaseAbstractLookupControlImpl<String>

Base utility class when lookups of custom numeric conditions should be implemented. Provides buitin expression parser and range checks, only custom conditions have to be implemented in descendant classes.

Method Detail

isMonetary

public final boolean isMonetary()

T if this control handles a monetary amount.

appendCriteria

protected ILookupControlInstance.AppendCriteriaResult appendCriteria(QCriteria<?> crit,
                                                                     QOperation op,

Throws:

Exception

checkNumber

protected void checkNumber(T value)

appendCriteria

@Nonnull
public ILookupControlInstance.AppendCriteriaResult appendCriteria(@Nonnull
                                                                           QCriteria<?> crit)

Description copied from interface: ILookupControlInstance

Evaluate the contents of the input for this lookup line; if the user has added data there then add the values to the query.

Specified by:

appendCriteria in interface ILookupControlInstance<String>

Specified by:

appendCriteria in class BaseAbstractLookupControlImpl<String>

Returns:

see ILookupControlInstance.AppendCriteriaResult

Throws:

Exception

scanOperation

protected QOperation scanOperation()

Checks the current position for a supported operation. If OK the appropriate operation code is returned and the current pos is advanced after it.

Returns:

parseNumber

protected T parseNumber(String in)

This delivers a number of the same type as the property by scanning the input string. I use the monetary amount scanner to allow for max flexibility in input, and the resulting BigDecimal will be converted to the appropriate type afterwards.

Parameters:

in -

Returns:

getValue

public String getValue()

Description copied from interface: ILookupControlInstance

Return the value entered into this control. This may return null.

Returns:

setValue

public void setValue(String value)

Description copied from interface: ILookupControlInstance

Sets the value in the control
