Method Details
-
getType
int getType()- Returns:
- The parameter buffer type identifier
-
addArgument
void addArgument(int argumentType) Add argument with no parameters.- Parameters:
argumentType- type of argument.
-
addArgument
Add string argument with the default encoding.- Parameters:
argumentType- type of argument.value- string value to add.
-
addArgument
Add string argument.- Parameters:
argumentType- type of argument.value- string value to add.encoding- encoding to use for conversion to bytes
-
addArgument
void addArgument(int argumentType, byte value) Add a byte argument.- Parameters:
argumentType- type of argument.value- byte value to add.
-
addArgument
void addArgument(int argumentType, int value) Add integer argument.- Parameters:
argumentType- type of argument.value- integer value to add.
-
addArgument
void addArgument(int argumentType, long value) Add long argument.- Parameters:
argumentType- type of argument.value- long value to add.
-
addArgument
void addArgument(int argumentType, byte[] content) Add array of bytes.- Parameters:
argumentType- type of argument.content- content of argument.
-
removeArgument
void removeArgument(int argumentType) Remove the first occurrence of the specified argument.- Parameters:
argumentType- type of argument to remove.
-
getArgumentAsString
Get argument as string.- Parameters:
argumentType- type of argument to find.- Returns:
- argument as string or
nullif nothing found.
-
getArgumentAsInt
int getArgumentAsInt(int argumentType) Get argument as int.- Parameters:
argumentType- type of argument to find.- Returns:
- argument as string or
0if nothing found.
-
hasArgument
boolean hasArgument(int argumentType) Check if this parameter buffer has specified argument.- Parameters:
argumentType- type of argument to find.- Returns:
trueif this buffer contains specified argument.
-
iterator
Returns an iterator over a copy of the parameters in this parameter buffer.It is safe to iterate over this iterator while modifying the parameter buffer. Changes will not be reflected in the iterator.
-
writeArgumentsTo
Writes the arguments in the implementation specific serialization into theOutputStream.- Parameters:
outputStream- TheOutputStreamto write to- Throws:
IOException- Errors produced by the output stream during writes
-
toXdrable
Xdrable toXdrable()- Returns:
Xdrableto write (and optionally read) this instance as Xdr.
-
toBytes
byte[] toBytes()Converts this parameter buffer to a byte array.This byte array includes the extra header-bytes (if any), but does not include the type information
- Returns:
- Byte array with serialization of this parameter buffer
- See Also:
-
toBytesWithType
byte[] toBytesWithType()Converts this parameter buffer to a byte array with type information.This byte array includes the type information and the extra header bytes (if any).
- Returns:
- Byte array with serialization of this parameter buffer
- See Also:
-
size
int size()- Returns:
- the number of parameters stored.
