Parameters:

columnIndex -

clear

public void clear()

Removes all mappings from this map (optional operation).

Specified by:

clear in interface java.util.Map

containsKey

public boolean containsKey(java.lang.Object key)

Returns true if this map contains a mapping for the specified key.

Specified by:

containsKey in interface java.util.Map

Parameters:

key -

containsValue

public boolean containsValue(java.lang.Object value)

Returns true if this map maps one or more keys to the specified value.

Specified by:

containsValue in interface java.util.Map

Parameters:

value -

entrySet

public java.util.Set entrySet()

Returns a set view of the mappings contained in this map. this method returns an unmodifiable Set

Specified by:

entrySet in interface java.util.Map

equals

public boolean equals(java.lang.Object o)

Compares the specified object with this map for equality.
Returns true if the given object is also a map and the two Maps represent the same mappings. More formally, two maps t1 and t2 represent the same mappings if t1.entrySet().equals(t2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.

Specified by:

equals in interface java.util.Map

Parameters:

o -

get

public java.lang.Object get(java.lang.Object key)

Returns the value to which this map maps the specified key.

Specified by:

get in interface java.util.Map

Parameters:

key -

hashCode

public int hashCode()

Returns the hash code value for this map. Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hashCodes of each entry in the map's entrySet view. This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two maps t1 and t2, as required by the general contract of Object.hashCode.

Specified by:

hashCode in interface java.util.Map

isEmpty

public boolean isEmpty()

Returns true if this map contains no key-value mappings.

Specified by:

isEmpty in interface java.util.Map

keySet

public java.util.Set keySet()

Returns a set view of the keys contained in this map.

Specified by:

keySet in interface java.util.Map

put

public java.lang.Object put(java.lang.Object key,
                            java.lang.Object value)

Associates the specified value with the specified key in this map (optional operation).

Specified by:

put in interface java.util.Map

Parameters:

key -

value -

putAll

public void putAll(java.util.Map t)

Copies all of the mappings from the specified map to this map (optional operation).

Specified by:

putAll in interface java.util.Map

Parameters:

t -

remove

public java.lang.Object remove(java.lang.Object key)

Removes the mapping for this key from this map if it is present (optional operation).

Specified by:

remove in interface java.util.Map

Parameters:

key -

public int size()

Returns the number of key-value mappings in this map.

Specified by:

size in interface java.util.Map

values

public java.util.Collection values()

Returns a collection view of the values contained in this map.

Specified by:

values in interface java.util.Map
