Constructor Detail

Result

public Result(Object responseData)

Constructs a "result" from data found in ResponseResult.getData().

public int getInt()

Gets the result item by coercing it to an int.

Throws:

NumberFormatException - if the value is not parsable as an int.

Gets the result item by coercing it to an byte.

Throws:

NumberFormatException - if the value is not parsable as an byte.

getShort

public short getShort()

Gets the result item by coercing it to an short.

Throws:

NumberFormatException - if the value is not parsable as an short.

getLong

public long getLong()

Gets the result item by coercing it to an long.

Throws:

getFloat

public float getFloat()

Gets the result item by coercing it to an float.

Throws:

NumberFormatException - if the value is not parsable as an float.

getDouble

public double getDouble()

Gets the result item by coercing it to an double.

Throws:

NumberFormatException - if the value is not parsable as an double.

getBoolean

public boolean getBoolean()

Gets the result item by coercing it to an boolean.

getProperty

public <V> Property<V> getProperty()

Gets the result item by casting it to a Property.

getVertexProperty

public <V> VertexProperty<V> getVertexProperty()

Gets the result item by casting it to a VertexProperty.

get

public <T> T get(Class<? extends T> clazz)

Gets the result item by casting it to the specified Class.
