Method Detail

write

public void write(java.io.DataOutput dos)
           throws java.io.IOException

Write this ChangeSet to a file stream.

Parameters:

dos - DataOutput interface implementer to use for the writing

Throws:

java.io.IOException - if write fails for any reason.

writeId

protected void writeId(java.io.DataOutput dos)
                throws java.io.IOException

Handle writing the ID field to the binary data stream (handles larger ID ranges in varying subclasses).

Specified by:

writeId in class GenericTaggedNode<ChangeSet>

Parameters:

dos - DataOutput to use to append the binary ID value

Throws:

java.io.IOException - if write fails for any reason

getId

public java.lang.Number getId()

Return the ID of this OSM record as a sub-class of Number.

Specified by:

getId in class GenericTaggedNode<ChangeSet>

Returns:

Number subclass instance

read

public static ChangeSet read(java.io.DataInput dis)
                      throws java.io.IOException

Read a ChangeSet from the provided input stream.

Parameters:

dis - DataInput interface implementer from which to read the ChangeSet

Returns:

a filled-in ChangeSet structure

Throws:

java.io.IOException - if the read failed for any reason

dup

public ChangeSet dup()

Create a deep copy of this ChangeSet. Similar to the Object method clone(), but without the exceptions and casting.

Specified by:

dup in class GenericTaggedNode<ChangeSet>

Returns:

copy of this ChangeSet

writeGPX

public void writeGPX(java.io.PrintStream ps)

Write this ChangeSet to the specified stream as the XML tags one element in GPX schema format.

Specified by:

writeGPX in class GenericTaggedNode<ChangeSet>

Parameters:

ps - PrintStream to write to

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.

See Also:

Object.equals(Object), System.identityHashCode(java.lang.Object)

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

See Also:

hashCode(), HashMap

compareTo

public int compareTo(ChangeSet o)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Specified by:

compareTo in interface java.lang.Comparable<ChangeSet>

Parameters:

o - the object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Throws:

java.lang.NullPointerException - if the specified object is null

java.lang.ClassCastException - if the specified object's type prevents it from being compared to this object.
