Method Detail

getFloat

public float getFloat()

Description copied from interface: FloatValue

Get the float representation of the current value.

NOTE: The value returned is not valid unless calling AnalyticsValue.exists() afterwards returns TRUE.

Specified by:

getFloat in interface FloatValue

Returns:

the current value

getDouble

public double getDouble()

Description copied from interface: DoubleValue

Get the double representation of the current value.

NOTE: The value returned is not valid unless calling AnalyticsValue.exists() afterwards returns TRUE.

Specified by:

getDouble in interface DoubleValue

Returns:

the current value

getString

public String getString()

Description copied from interface: StringValue

Get the String representation of the current value.

NOTE: The value returned is not valid unless calling AnalyticsValue.exists() afterwards returns TRUE.

Specified by:

getString in interface StringValue

Returns:

the current value

getObject

public Object getObject()

Description copied from interface: AnalyticsValue

Get the object representation of the current value.

Specified by:

getObject in interface AnalyticsValue

Returns:

the current value

exists

public boolean exists()

Description copied from interface: AnalyticsValue

Check whether the current value exists.
NOTE: The result of this method is only guaranteed after any get<Type>() method is called.

Specified by:

exists in interface AnalyticsValue

Returns:

whether the current value exists

streamFloats

public void streamFloats(FloatConsumer cons)

Description copied from interface: FloatValueStream

Stream the float representations of all current values, if any exist.

Specified by:

streamFloats in interface FloatValueStream

Parameters:

cons - The consumer to accept the values

streamDoubles

public void streamDoubles(DoubleConsumer cons)

Description copied from interface: DoubleValueStream

Stream the double representations of all current values, if any exist.

Specified by:

streamDoubles in interface DoubleValueStream

Parameters:

cons - The consumer to accept the values

streamStrings

public void streamStrings(Consumer<String> cons)

Description copied from interface: StringValueStream

Stream the String representations of all current values, if any exist.

Specified by:

streamStrings in interface StringValueStream

Parameters:

cons - The consumer to accept the values

streamObjects

public void streamObjects(Consumer<Object> cons)

Description copied from interface: AnalyticsValueStream

Stream the object representations of all current values, if any exist.

Specified by:

streamObjects in interface AnalyticsValueStream

Parameters:
