使用说明GydF4y2Ba
The performance of this transformer is dependent on the amount of memory allocated to the Java Virtual Machine (JVM). The following environment variables allow you to specify memory available to Java Plugins:
- fme_jvm_min_heap_size：初始化JVM的初始堆大小。如果未设置，默认值为1024k。GydF4y2Ba
- fme32_jvm_min_heap_size：与fme_jvm_min_heap_size相同，但适用于Windows上的32位FME桌面，如果设置，则优先于fme_jvm_min_heap_size。GydF4y2Ba
These variables must be set in multiples of 1024 and greater than 1 MB. To indicate kilobytes, megabytes, or gigabytes, appendK.GydF4y2BaorK.GydF4y2Ba那GydF4y2BamGydF4y2BaormGydF4y2Ba， 或者GydF4y2BaGGydF4y2BaorGGydF4y2Barespectively. For example, any of these values is acceptable:
6291456.GydF4y2Ba
6144K.GydF4y2Ba
6m
- fme_jvm_max_heap_size：初始化JVM的最大堆大小。如果未设置，则默认值为16384K。GydF4y2Ba
- FME32_JVM_MAX_HEAP_SIZE: Same as FME_JVM_MAX_HEAP_SIZE, but applies to 32-bit FME Desktop on Windows, and if set, takes precedence over FME_JVM_MAX_HEAP_SIZE.

登记每一个独特的ID是不同的ndroid device/application pair, so it cannot be shared between different applications. When configuring the GCMMessenger to work with a new application, new registration IDs must be acquired.
To register an Android application to the Google Cloud Messaging service, send acom.google.android.c2dm.intent.REGISTERintent. The registration ID is returned to the application in an intent extended string fieldregistrign_id.GydF4y2Ba。这个过程详述了GydF4y2Ba编写使用GCM的Android应用程序GydF4y2Ba。GydF4y2Ba

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click
beside the applicable parameter. For more information, see变换器参数菜单选项GydF4y2Ba。GydF4y2Ba
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
