Constructor Detail

StringColumnConstraint

protected StringColumnConstraint(java.lang.String patternString,
                                 java.lang.String errorMessage)

Constructs a new StringColumnConstraint using the given pattern and patternString.

Parameters:

patternString - the user entered string to form the pattern used to accept column values.

errorMessage - the text to display in an empty editor textfield.

StringColumnConstraint

protected StringColumnConstraint(java.lang.String patternString)

Constructs a new StringColumnConstraint using the given pattern and patternString, using the default hint text that explains that you can use globbing characters.

Parameters:

patternString - the user entered string to form the pattern used to accept column values.

Method Detail

getGroup

public java.lang.String getGroup()

Description copied from interface: ColumnConstraint

Returns a "group" string that is used to logically group column constraints for presentation to the user

Specified by:

getGroup in interface ColumnConstraint<java.lang.String>

Returns:

the group this constraint belongs to.

accepts

public boolean accepts(java.lang.String value,
                       TableFilterContext context)

Description copied from interface: ColumnConstraint

Compares value against the current constraint value to determine acceptance; true if value satisfies the constraints' value, false otherwise

Specified by:

accepts in interface ColumnConstraint<java.lang.String>

Parameters:

value - the column value to be tested.

context - provides additional information about the the table and its data. This allows the filter to base its decision on information other than just the column value.

Returns:

true if the column value passes the constraint, false otherwise

generateMatchesPattern NEW

protected abstract java.util.regex.Pattern generateMatchesPattern(java.lang.String value)

generateFindsPattern NEW

protected java.util.regex.Pattern generateFindsPattern()

getEditor

public ColumnConstraintEditor<java.lang.String> getEditor(ColumnData<java.lang.String> columnDataSource)

Description copied from interface: ColumnConstraint

Returns a ColumnConstraintEditor which will provide gui components for users to edit the constraint values.

Specified by:

getEditor in interface ColumnConstraint<java.lang.String>

Parameters:

columnDataSource - This provides the constraint with access to the column data in the table model as well as the DataProvider of the table (if it has one)

Returns:

A columnConstraintEditor for editing the constraints value.

copy

public abstract ColumnConstraint<java.lang.String> copy(java.lang.String newPatternString)

subclasses must override to generate new versions of themselves but with a new pattern string.

Parameters:

newPatternString - the new string to use for creating the match pattern.

Returns:

a new ColumnConstraint that is the same type as this constraint but with a new range defined.

getPatternString

public java.lang.String getPatternString()

Returns the pattern string for this constraint.

Returns:

the pattern string for this constraint.

getColumnType

public java.lang.Class<java.lang.String> getColumnType()

Description copied from interface: ColumnConstraint

Returns the column type that this constraint can be used to filter.

Specified by:

getColumnType in interface ColumnConstraint<java.lang.String>

Returns:

the column type

getConstraintValueTooltip

public java.lang.String getConstraintValueTooltip()

Description copied from interface: ColumnConstraint

returns a description of the constraint suitable for displaying in a tooltip

Specified by:

getConstraintValueTooltip in interface ColumnConstraint<java.lang.String>

Returns:

a description of the constraint.

getConstraintValueString

public java.lang.String getConstraintValueString()

Description copied from interface: ColumnConstraint

Returns the "value" of the constraint in string form

This is used for serializing the constraint.

Specified by:

getConstraintValueString in interface ColumnConstraint<java.lang.String>

Returns:

the "value" of the constraint in string form.

parseConstraintValue

public ColumnConstraint<java.lang.String> parseConstraintValue(java.lang.String newValue,
                                                               java.lang.Object dataSource)

Description copied from interface: ColumnConstraint

Parses the constraint value string for deserialization purposes.

Specified by:

parseConstraintValue in interface ColumnConstraint<java.lang.String>

Parameters:

newValue - the value of the constraint in string form.

dataSource - the DataSource from the Table.

Returns:

a new ColumnConstraint
