Set the minimum value for the given dimension.

指定者:

setMin 在接口中 Spatial

参数:

dim - the dimension

x - the value

max

public float max(int dim)

从接口复制的说明: Spatial

Get the maximum value for the given dimension.

指定者:

max 在接口中 Spatial

参数:

dim - the dimension

返回:

dim - the dimension

x - the value

clone

public Spatial clone(long id)

从接口复制的说明: Spatial

Creates a copy of this Spatial object with different id.

指定者:

clone 在接口中 Spatial

参数:

id - for the new Spatial object

返回:

a clone

getId

public long getId()

从接口复制的说明: Spatial

toString 在类中 Value

hashCode

public int hashCode()

指定者:

hashCode 在类中 Value

equals

public boolean equals(Object other)

从类复制的说明: Value

Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00.

指定者:

equals 在类中 Value

参数:

other - the other value

返回:

true if they are equal

compareTypeSafe

public int compareTypeSafe(Value v,

                           CastDataProvider provider)

从类复制的说明: Value

Compare this value against another value given that the values are of the same data type.

指定者:

compareTypeSafe 在类中 Value

参数:

v - the other value

mode - the compare mode

provider - the cast information provider

返回:

0 if both values are equal, -1 if the other value is smaller, and 1 otherwise

equalsIgnoringId

public boolean equalsIgnoringId(Spatial o)

Check whether two objects are equals, but do not compare the id fields.

指定者:

equalsIgnoringId 在接口中 Spatial

参数:

o - the other key
