Method Detail

asBool

Boolean asBool(K key)

Convert the value with given key to a Boolean, using Boolean.valueOf(String).

Parameters:

key - The key of the value to convert

Returns:

The result of Boolean.valueOf(String) if the value is not null, else null

asByte

Byte asByte(K key)

Convert the value with given key to a Byte, using Byte.valueOf(String).

Parameters:

key - The key of the value to convert

Returns:

The result of Byte.valueOf(String) if the value is not null, else null

asShort

Short asShort(K key)
       throws NumberFormatException

Convert the value with given key to a Short, using Short.valueOf(String).

Parameters:

key - The key of the value to convert

Returns:

The result of Short.valueOf(String) if the value is not null, else null

Throws:

NumberFormatException - if the value cannot be coerced

asInt

Integer asInt(K key)
       throws NumberFormatException

Convert the value with given key to a Integer, using Integer.valueOf(String).

Parameters:

key - The key of the value to convert

Returns:

The result of Integer.valueOf(String) if the value is not null, else null

Throws:

NumberFormatException - if the value cannot be coerced

asLong

Long asLong(K key)
     throws NumberFormatException

Convert the value with given key to a Long, using Long.valueOf(String).

Parameters:

key - The key of the value to convert

Returns:

The result of Long.valueOf(String) if the value is not null, else null

Throws:

NumberFormatException - if the value cannot be coerced
