Field Detail

### NONE

    public static final Limit NONE

Constructor Detail

### Limit

    public Limit(int rowLimit)

  Create a limit on the number of rows.

  Parameters:
    `rowLimit` - the maximum number of rows
  Throws:
    `IllegalArgumentException` - if the row limit is negative

### Limit

    public Limit(int rowLimit,
                 int offset)

  Create a limit on the number of rows and the number of initial rows to skip.

  Parameters:
    `rowLimit` - the maximum number of rows
    `offset` - the number of rows to skip before beginning the results
  Throws:
    `IllegalArgumentException` - if the row limit is negative, or if the offset is negative

Method Detail

### offset

    public final int offset()

  Get the number of rows skipped before the results begin.

  Returns:
    the offset; always 0 or a positive number

### rowLimit

    public final int rowLimit()

  Get the maximum number of rows that are to be returned.

  Returns:
    the maximum number of rows; never negative, or equal to `Integer.MAX_VALUE` if there is no limit

### isUnlimited

    public final boolean isUnlimited()

  Determine whether this limit clause is necessary.

  Returns:
    true if the number of rows is not limited and there is no offset, or false otherwise

### hasRowLimited

    public final boolean hasRowLimited()

  Determine whether this limit clause defines a maximum limit

  Returns:
    true if the number of rows are limited, or false if there is no limit to the number of rows

### isOffset

    public final boolean isOffset()

  Determine whether this limit clause defines an offset.

  Returns:
    true if there is an offset, or false if there is no offset

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`
  See Also:
    `Object.toString()`

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `Object`
  See Also:
    `Object.hashCode()`

### equals

    public boolean equals(Object obj)

  Overrides:
    `equals` in class `Object`
  See Also:
    `Object.equals(java.lang.Object)`

### accept

    public void accept(Visitor visitor)

  Accept the supplied visitor, which should call back to the visitor to complete the double-dispatch operation.

  Specified by:
    `accept` in interface `Visitable`
  Parameters:
    `visitor` - the visitor; never null
  See Also:
    `Visitable.accept(org.modeshape.graph.query.model.Visitor)`

### withRowLimit

    public Limit withRowLimit(int rowLimit)

### withOffset

    public Limit withOffset(int offset)
