Class SelectSelector

    java.lang.Object

All Implemented Interfaces:
  java.lang.Cloneable, FileSelector, SelectorContainer

    public class SelectSelector

extends BaseSelectorContainer

This selector just holds one other selector and forwards all requests to it. It exists so that there is a single selector type that can exist outside of any targets, as an element of project. It overrides all of the reference stuff so that it works as expected. Note that this is the only selector you can reference.

Since:
  1.5

`SelectSelector()` Default constructor.

Method Summary
`void` | `appendSelector(FileSelector selector)` Add a new selector into this container.
`FileSelector[]` | `getSelectors(Project p)` Returns the set of selectors as an array.
`boolean` | `hasSelectors()` Indicates whether there are any selectors here.
`boolean` | `isSelected(java.io.File basedir, java.lang.String filename, java.io.File file)` Returns true (the file is selected) only if the if property (if any) exists, the unless property (if any) doesn't exist, and the contained selector (if any) selects the file.
`boolean` | `passesConditions()` Ensures that the selector passes the conditions placed on it with `if` and `unless`.
`int` | `selectorCount()` Gives the count of the number of selectors in this container
`java.util.Enumeration` | `selectorElements()` Returns an enumerator for accessing the set of selectors.
`void` | `setIf(java.lang.String ifProperty)` Sets the if attribute to a property which must exist for the selector to select any files.
`void` | `setUnless(java.lang.String unlessProperty)` Sets the unless attribute to a property which cannot exist for the selector to select any files.
`java.lang.String` | `toString()` Convert the Selectors within this container to a string.
`void` | `verifySettings()` Makes sure that there is only one entry, sets an error message if not.

Constructor Detail

### SelectSelector

    public SelectSelector()

  Default constructor.

Method Detail

### toString

    public java.lang.String toString()

  Description copied from class: `BaseSelectorContainer`
  Convert the Selectors within this container to a string. This will just be a helper class for the subclasses that put their own name around the contents listed here.

  Overrides:
    `toString` in class `BaseSelectorContainer`
  Returns:
    a string describing this object

### hasSelectors

    public boolean hasSelectors()

  Indicates whether there are any selectors here.

  Specified by:
    `hasSelectors` in interface `SelectorContainer`
  Overrides:
    `hasSelectors` in class `BaseSelectorContainer`
  Returns:
    whether any selectors are in this container

### selectorCount

    public int selectorCount()

  Gives the count of the number of selectors in this container

  Specified by:
    `selectorCount` in interface `SelectorContainer`
  Overrides:
    `selectorCount` in class `BaseSelectorContainer`
  Returns:
    the number of selectors in this container

### getSelectors

    public FileSelector[] getSelectors(Project p)

  Returns the set of selectors as an array.

  Specified by:
    `getSelectors` in interface `SelectorContainer`
  Overrides:
    `getSelectors` in class `BaseSelectorContainer`
  Parameters:
    `p` - the current project
  Returns:
    an array of selectors in this container

### selectorElements

    public java.util.Enumeration selectorElements()

  Returns an enumerator for accessing the set of selectors.

  Specified by:
    `selectorElements` in interface `SelectorContainer`
  Overrides:
    `selectorElements` in class `BaseSelectorContainer`
  Returns:
    an enumerator that goes through each of the selectors

### appendSelector

    public void appendSelector(FileSelector selector)

  Add a new selector into this container.

  Specified by:
    `appendSelector` in interface `SelectorContainer`
  Overrides:
    `appendSelector` in class `BaseSelectorContainer`
  Parameters:
    `selector` - the new selector to add

### verifySettings

    public void verifySettings()

  Makes sure that there is only one entry, sets an error message if not.

  Overrides:
    `verifySettings` in class `BaseSelector`

### passesConditions

    public boolean passesConditions()

  Ensures that the selector passes the conditions placed on it with `if` and `unless`.

  Returns:
    true if conditions are passed

### setIf

    public void setIf(java.lang.String ifProperty)

  Sets the if attribute to a property which must exist for the selector to select any files.

  Parameters:
    `ifProperty` - the property to check

### setUnless

    public void setUnless(java.lang.String unlessProperty)

  Sets the unless attribute to a property which cannot exist for the selector to select any files.

  Parameters:
    `unlessProperty` - the property to check

### isSelected

    public boolean isSelected(java.io.File basedir,
                              java.lang.String filename,
                              java.io.File file)

  Returns true (the file is selected) only if the if property (if any) exists, the unless property (if any) doesn't exist, and the contained selector (if any) selects the file. If there is no contained selector, return true (because we assume that the point was to test the if and unless conditions).

  Specified by:
    `isSelected` in interface `FileSelector`
  Specified by:
    `isSelected` in class `BaseSelectorContainer`
  Parameters:
    `basedir` - the base directory the scan is being done from
    `filename` - the name of the file to check
    `file` - a java.io.File object for the filename that the selector can use
  Returns:
    whether the file should be selected or not
